摘要
提出了一种基于二次曲面拟合的插值算法。该算法对最近邻插值算法中的阶梯状直边界起很好的平滑作用,有效地解决了线性插值算法中的亮度损失问题,避免了高阶插值算法运算量巨大、严重耗时等局限。该算法具有较高的应用价值。
A kind of interpolation algorithm based on quadratic surface fitting is addressed in this paper. It has very good smoothing function to ladder straight edge which can not be avoided in nearest-neighborhood interpolation. It can solve brightness loss problem in linear interpolation. It also can avoid great mathematical operations, serious time loss and so on the limitation. This algorithm has the high application value.
